Our regularly updated S&P 500 companies list shows you what companies are currently in the S&P 500 index and provides the ticker symbol, market capitalization, and PE Ratio. The companies listed on the S&P 500 index are the USA’s largest and most successful companies. The index is managed by the Standard & Poor rating agency. A company becomes a constituent of the S&P 500 when its market capitalization (total outstanding shares X share price) is ranked in the top 500. The S&P 500 Index is widely regarded as the best representation of the US stock market and is tracked by many professional and amateur investors. It tracks the performance of 500 of the largest companies in the US based on their market capitalization. These stocks are weighted proportionally to their size. As a result, large companies have more influence over the index than smaller ones. The S&P 500 Index lists the largest 500 companies (by market capitalization) traded on the U.S. Stock Exchanges. Hence, it includes companies traded on the Nasdaq and the New York Stock Exchange (NYSE). It is typically used as the benchmark against which all US investments are measured. The term beat the market usually refers to an investment that returns better results than the S&P 500. The PE Ratio is only useful when comparing companies in the same industrial sector. This is why you can easily find stocks that could be potentially undervalued by listing companies by Sector, Market Capitalization, and PE ratio. Knowing what companies are in which sector helps you formalize a stock sector rotation strategy. If no PE Ratio is listed, it means the company is not currently making a profit.
